DISH-WASHING MACHINE.

To all whom it may concern:

Be it known that 1, Isaac L. FnAnnnM, a citizen of the United States,residing at Indianapolis, in the county of Marion and. State of Indiana,have invented certain new and useful Improvements in Dish-WashingMachines, of which the following is a speci fication.

My present invention consists in certain improvements upon the machineshown and described in my Letters Patent No. 818,427 dated April 24,1906. Said invention will be first fully described, and the novelfeatures thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof,and on which similar reference characters indicate similar parts, Figure1 is a perspective view of a machine embodying my said invention; Fig. 2a top or plan view of that portion within which the washing of thedishes is done; Fig. 3 a longitudinal vertical sectional view as seenwhen looking in the direction indicated by the arrows from the brokenline 3 3 in Fig. 2; Fig. --4 a transverse vertical sectional view asseen when lookin in the direction indicated by the arrows rom the brokenlines 4 4 in Figs. 2 and 3, and Fig. 5 a perspective view of a basketsuch as is used to contain the soiled dishes when they are placed inthis machine for purposes of cleansing.

The interior mechanism and arrangement is very similar to that shown anddescribed in my said Patent No. 818,427, but is of a somewhat improvedform.

The machine consists, generally speaking, of an oblong rectangular tank21 containing (as in said former patent) twocompart" merits, one, 22,for the primary washing operation, and the other, 23, for the rinsing.-Within the compartment 22 are the tracks 24 upon which the cage 25 ismounted and reciprocates. Upon that end of the structure which captainsthe rinsing tank 23, T

have now added a drain-board 26, and I have provided, referably belowsaid drain board, a shelf 2 upon whicha motor28 far driving themachinemay be placed.

In my improved machine I attach to the frame ,25 a curved arm 31 whichextends over to outside the wall of tank 21. To the end of this arm 31 Iconnect a pitman 32, Which, in turn, connects to a crank-wheel 38mounted on: shaft 34. Also on said shaft 34 Specification of LettersPatent.

Application filed March as,

1909. Serial no. aaaeao."

The drain connections, for the purpose of drawing off the scum andgrease from the top of the water, are,-in my improved ma chine removedfrom inside the tanks to the outside. Branch pipes 41 and 42 extend inthrough the Wall of tank 21 near the top, one on either side oftheipartition 29 which separates the two chambers 22. and 23. Theseunite in a central pipe 43 which leads down and connects with the mainpipe 44. The pipes 46 and 47 leading through the bottoms of the twocompartments also con nect with said main pipe 44.

In performing the washing or cleansing operation, asformerly, I placethe soiled dishes Within one or more baskets 51, and place said basketswithin the cage 25. The cage is then driven back and forth through thewater, and the cleansing operation is thus performed.

in my former machine, especially when driven at considerable speed, oneresult was a considerable splashing and slopping of the water. l[ havediscovered that by securing within the compartment a series of inclinedwings, this is almost wholly overcome. I therefore place on each of thetwo sides wings 61 and 62, inclined in opposite directions,

as most plainly shown in Fig.3 of the drawing. These wings,as abovestated, have the effect to very largely control the splashing andslopping, and render the operation very much more neat and cleanly, andaid materially in forcing the water through the basket and over thedishes. The application of a motor and connecting mechanism also rendersthe operation of the machine much more steady and uniform, with aconsequent improvement of result.

Having thus fully described my said invention, what ll claim as new, anddesire to secureby Letters Patent, is,

1. The combination, in a dish washing machine, of a tank, trackstherein, a reciproeating cage mounted on said tracks, and means forimparting motion thereto, the said compartment of the tank wherein thecage is positioned having inclined wings secured to its inner surfacewherebythe tendency to splash is overcome.

2. The combination, in a dish washing ma- Patented Feb, 1, into.

eating cage mounted on said tracks, and means for imparting motionthereto, the said compartment of the tank wherein the cage is positionedhaving inclined wings secured to its inner surface whereby the tendencyto splash is overcome, some of said wings being inclined in onedirection and some in the its inner surface whereby the tendency tosplash is overcome, the wings at each end of the' tank being inclined uwardly toward the wings at the other end 0 the tank.

4. The combination, in a dish washing machine, of a tank, trackstherein, a reciproeating cage arranged on the tracks within the tank andwholly below the top thereof, a curved arm extending from said cage overthe upper edge of the wall of the tank to a point outside horizontallyopposite the cage,

a pitman connected to said curved arm at its outer end at a point belowthe level of thetop of the cage, and a motor connected to said pitmanwhereby the cage is actuated.

In witness whereof, I, haue hereunto set my hand and seal atIndianapolis, Indiana, this twenty-fifth day of March,A. D. one thousandnine hundred and nine.
